SPECIFICATION forming part of Letters Eatent No. 545,817, datedSeptember 3, 1895.

Application filed July 26, 1894.

T0 on whom it may concern Be it known that I, JOSEPH L. PUTEGNAT, acitizen of the United States, residing at Brownsville, in the county ofCameron and State of Texas,have invented certain new and usefulImprovements in Syringes; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it 'appertains to make and use thesame.

This invention aims to provide a combined syringe and reservoir whichcan be conveniently carried in the pocket and when in use will inject orthrow a given amount of fluid. The syringe is essentially apiston-operated device, as such is preferable to the bulb for efficicncyand compactness and is conveniently operated. Inits special organinationthe device is particularly adapted for males and treatment of diseasesto which they are heir, and is light, neat, and compact, so as to beeasilycarried in the pocket.

The improvement will be more fully set forth hereinafter, pointed out inthe claim, and shown in the annexed drawings, in which- Figure 1 is aside elevation of the invention, parts being broken away. Fig. 2 is aView similar to Fig.1, showing the syringe in readiness for use. -Fig. 3is a section on the line m a: of Fig. 1.

Similar letters refer to corresponding parts in the several views.

The reservoir B is flat and of a size to be conveniently carried in thepocket and has an opening closed by a suitable cap or stopper E. Acylinder or barrel 0 is formed on one edge of the reservoir andcommunicates with the latter through an opening D near the butt of thesaid barrel. The barrel terminates in a discharge-nozzle H, suitablyformed to meet the special requirements and direct the fluid to the seatof the ailment. This nozzle projects beyond the edge of the reservoirfor convenience in use; but, if required, it may terminate flush, ornearly so, with the said edge. A cap F is adapted to be fitted on thenozzle'to protect it from injury when the device is not in use. Thepiston I is of usual formation and is operated in the barrel 0 by a stem2', which works through acap J, provided to close the butt end of thebarrel. The caps J and E are on the same end of the reservoir and areprotected by a cover A, which in the present instance is hinged atSerial No. 518,682- (No model.)

one end to the reservoir and is secured at the opposite end by a clasp Gon the opposite side of the reservoir. The cover A may be of any of theusual types, and, besides protecting the end of the stem 2' and the capsJ and E, gives a symmetrical and neat appearance to the device.

The fluid used in the treatment of the particular disease is placed inthe reservoir in the required or measured quantity through the openingclosed by the cap E. The device in the form shown in Fig. 1 canbeconveniently carried in the pocket for ready use. When it is desiredto use the syringe, the cover A is thrown out of the way, the pistondrawn to the butt end of the barrel, the cap F removed, and thereservoir turned so that the barrel occupies the lowest position. fluidwill pass from the reservoir into the barrel through the opening D. Onoperating the piston the fluid will be discharged through the nozzle H.The piston can be withdrawn and the barrel again charged without thenecessity of removing the nozzle from engagement with the diseased part.Thus the oontents of the reservoir can be wholly applied to theseat ofthe disorder at one operation or the contents of a simple charge can beexpelled from the barrel and the balance reserved for futureapplication.

The parts A, B, and G are formed of hard rubber or similar material, ascelluloid, which is light and durable and capable of bolding a medicinalfluid without being affected thereby.

I claim The combination with the reservoir B having a filling openinginoneend and a cap E closing the said opening, of a barrel 0 formed atone-side of the reservoir and having an opening D adjacent to its upperor inner end, a cap J closing the barrel, a discharge nozzle for thebarrel, a piston working in the barrel, a stem secured to said pistonand projecting through the cap J, a protecting cap or cover .A for theprojecting stem, and the cap F, the whole forming a neat compact deviceadapted to be carried in the pocket, as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH L. PUTEGNAT.
